Specication of Letters Patent..

To all lwhom t may concern.'

Be it known that I, RICHARD a citizen of the United States, Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in N ut-Mills, of which the following is a specification.

his invention relates nut mills, and

. GREENE,

ployed for grinding peanuts and similar materials. The olbject of provide improvements inthe construction of such mills, and `also to provide in combination with the feeding mechanism means for automatically supplyinga proportion of seasoning material, such for example, as salt.

cAccording to this invention, a nut mill of improved constructionpermitting ready disassembling for cleaning, etc., is provided in combination with power operated means for automatically supplying salt or other seasoning material, so that the seasoning material will be thoroughly incorporated with the nuts at the time they are ground.

n the accompanying drawings, Figure l partly in section, of the improved machine;

ig. 2 is an end elevation seen from the left of Fig. 1, and Fig. 3 is a plan view;

Fig. 4 is a detail of the salt feeding mechanism, and F Fig. 5 is a section on the line 5-5 of 1 represents a base carrying bearings 2-2 in which is journaled the sleeve 11 carrying shaft 3 having 'feeding worm 4, and the @finding cone 5, removably fastened thereto by the scraping nut 56. he grinding cone 5 fits within the stat1onary cone 6 mounted in the base, and 7 represents a cooling water jacket. rl `he nuts are fed by the worm 4 and forced out between the grinding cone 5 and the stationary cone 6 into a removable casing 8 having a discharge spout 9. The sleeve 11 is separably fastened to shaft 3 by pin 12 passing through collar 13 at one end, so that the sleeve 11 turns with the shaft 3. By disconnecting the shaft from the pin, the shaft 3 carrying the movable cone 5 can be' reend-wise when the case 8 is removed.

his avoids disturbing the other driving parts of the machine, all of which are mounted on the sleeve 11.

16 is the end bearing for sleeve 11, and

residing at 1, the chute 'shaft 46, and connected with loosely mounted on this sleeve is the drivin pulley 17, which is connected by clutch 18 to a clutch hub 19, screw 20. The clutch 18 is operated by toggle links 21 carried by the clutch yoke 22 on the hub 19. The clutch yoke 22 is connected to a ring 23 which latter is connected by side links 24 to the operating lever 25. The links 21 are adjustable by means of turn buckles 27. 28 is a ball thrust bearing between the clutch and th ounted on the sleeve 1l is a driving pulley 29 carrying a h runs over a driving pulley 31 on shaft 32, which operates the salt shakin mechanism. The distance between the grin ing surfaces of grinding cone 5 and stationary cone 6 is adjusted by means of a lever 33 pivoted on the base l at 34 and engaging a collar 14, to operate against spring 26. By operating the hand wheel 35 on threaded 33 the entire sleeve 11, shaft 3 and inder 5 can beshifted longitudinally. '.lgl-ie lever also holds the spring under compression while the shaft is being removed and inserted.

The nuts are put into a hopper 38 and fall by gravity through the chute 39 to the inner or right-end of the worm 4. As seen in Fig.

39 is made of material and lits over a iiange 40 carried by the base, and opening through Vthe casing directly to the worm. The hopper 38, in order to save-space, is made round, and one corner of it is cut out inorder to receive the salt receptacle 41: As seen 1n Fig. 4, the salt having an inclined shaking bottom 42 similar to'a trough, and supported at an inclined position so as to slide transversely on pins 43. 44 represents a gate at the lower end which is adjusted to vary the opening by means of a hand-lever 45 mounted on the gate 44 by moves over a The handle 45 160 to the yoke 48 which is engaged y the eccentric 50. 51 are exible Haps whichprevent the salt from working up and around theA sides of the trough 42. From the lower end of trough 42, the Salt falls into a pocket 52 and then slides by gravity into the chute 39. The feed of the nuts is controlled by a sliding gate 54, which is set in the desired position by set screw 55.

The advantageous features of this machine reside in the facility with which .the grinding cone 5 can be removed independently of the driving mechanism, simply by disconnecting the sleeve 11 from the shaft 3; the adjustability of the clutch; and the combination'of the4 automatic salt feeding mechanism having its own means of adjustment. A further feature of advantage of this machine resides in its compactness an in the arrangement of the parts, so that the operator 'can te at a glance not only the proportionofsalt which is being fed, but also Vthe proportion of nuts. It will be seen that by this machine, a uniformly seasoned product will4 be produced with any given adjustment, which, so far asl am aware, has not heretofore been accomplished in mills of this class. This invention is espe- Laeoevs cially useful in the manufacture of so-called peanut and other nut butters, but is applicable to various other purposes without dearture from the scope of the invention. The details of construction herein shown are also capable of various modications and changes without departing from the scope of the appended claim.

I claim:

A nut mill comprising a frame carrying a stationary and a movable grinder, a screw connected with the movable grinder, a sleeve journaled in the frame and having a separable driving connection with said f screw, means for driving the sleeve, means on the frame for longitudinally adjusting the sleeve with the feed screw and movable grinder, the feed screw and movable grinder` being removable laterally of the stationary grinder upon being disconnected from the sleeve independently of `the driving means and without aecting the adjustment.
